Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

- Record min/max LBR cycles (>= Skylake) and add 'perf annotate' TUI
  hotkey to show it (c) (Jin Yao)

- Fix machine->kernel_start for PTI on x86 (Adrian Hunter)

- Make machine->env->arch always available, e.g. in 'perf top', not
  just when reading that info from perf.data files (Adrian Hunter)

- Reduce the number of files read at 'perf' start, leaving information such as
  cacheline size, tracefs mount point determination, max_stack, etc, to be
  lazily read as tools needs then (Arnaldo Carvalho de Melo)

- Fix up BPF include and examples install messages (Arnaldo Carvalho de Melo)

- Fix up callchain addresses and symbol offsets in 'perf script', to help
  correlating with objdump output (Sandipan Das)
